Miller and Lauzon meet on the main card of the pay-per-view event, which takes place Dec. 29 at MGM Grand Garden Arena in Las Vegas.

Heavyweights Roy Nelson and Shane Carwin were most recently selected for out-of-competition testing, which was re-instituted in late 2011, in advance of their fight at The Ultimate Fighter 16 Finale on Dec. 15. Both passed. (Carwin later withdrew from the bout with a knee injury.)

Miller (21-4 MMA, 10-3 UFC), who stepped in for an injured Gray Maynard at UFC 155, returns to action after losing a No. 1 contender’s bout to Nate Diaz at UFC on FOX 3 in May. In 13 octagon appearances, the New Jersey native has fallen short just three times, all against champions or top title contenders.

Lauzon (22-7 MMA, 9-4 UFC) most recently fought at UFC on FOX 4 and notched a third-round submission win over Jamie Varner, which earned him his ninth performance bonus inside the octagon, including six “Submission of the Night” awards.
